I. How do you say \(5^3\)

 

Really think about these and know that your correct and your response is not just out of habit. I would like to believe it is either "5 to the 3rd" or "5 index 3" but certainly not "5 to the 3rd power" as the power in this expression would be 125.

 

II.   \(2\sqrt{2}\)

III.  \(4(7+8(x))\)

IV.  \(f'''(x)=14x^5\)

V.  \(12_{9x}\)

VI.   \(4^{2^3}\)

VII.  \(ø\)

VIII.  \(4 ÷ 5\)

not as a faction but as a legit division so do not post "4 fifths" and please not "4 divided by 5" because surely there is a more mathematical way to say it... You surely would not say "4 added 5" in a class of peers, now would you?

IX. \(\left\{19x^{5\pi }|x\ge 5\right\}\)

X. \(^3\sqrt{7}\sqrt{4}\)

XI. \(4e^\phi \)

XII. \(14-7 - 14^2\)

XIII. \(sin θ = 5 (cot θ)^2\)

 

IVX. (8, 2, 4)

I. Five cubed

II. Two root two

III. Four times (slight pause!) seven plus eight x

IV. F triple prime of x equals fourteen times x to the power five

V. Twelve sub nine x

VI. Four to the power two cubed

VII. Zero!

VIII. Four divided by five (I don't understand your objection to this! It is certainly mathematical. For addition I wouldn't say four added five, but I would say four plus five.)

IX. The set of values of 19 times x to the power five pi such that x is greater than or equal to 5

X. The cube root of seven times root four

XI. Four times e to the power phi

XII. Fourteen minus seven minus fourteen squared

XIII. Sine theta equals five times cot theta squared

XIV. The set of integers eight, two and four

 

There is some ambiguity in a few of the above of course, but that's why we use mathematical symbols, to avoid the ambiguity!  It would be possible to express these in words without ambiguity, but  the penalty is that many more words would be needed!
