hard to explain

how?

ya i do

I get the following:

What is the equation for the statement: The result of subtracting a number from 3/4 is 7?

Let the number be=N

3/4 - N =7 subtract 3/4 from both sides

-N = 6 1/4 multiply both sides by -1

N = -6 1/4

What is 60% subtracted from $130

60/100 x 130 =$78.00

$130.00 - $78.00 =$52.00

Thank you!!

16^(5/4) → (16^(1/4))^5 → 2^5 → 32

.

10^10^12

Bravo Alan: excellent breakdown. Kudos!!!.

16^5/4 ?

Depends on the expression and the exponent!  Do you have a specific example in mind?

.

(1/2)log₂ 36 → log₂ 36^1/2 → log₂ 6

So:  (1/2)log₂ 36 - log₂ 3 →  log₂ 6 -  log₂ 3 → log₂(6/3) → log₂ 2 → 1

.

As follows:

.

log(1/10) = log(10^-1) = -1*log(10) = -1  (Assuming log is log to the base 10)

In step 4) I should have said: "... the two-thousand-five-hundredth root ..."  not "...the one-thousand-two-hundred-and-fiftyth root...".  I obviously had a senior moment!!!

Hallo Guest!

(1/1000)^(-1/3)

(1/1000)^(-1/3)  = (10^-3)^(-1/3) = 10¹ = 10

(1/1000)^(-1/3) = 10

81^{(-3/2)*(-1/2)}

81^(-3/2)*^(-1/2) = 3^{4*(-3/2)*(-1/2)}  = 3³

(81(-3/2) (-1/2) = 27

Greeting asinus :- )

It might help to think of the meaning in stages as follows:

.

8p^2 - 18   =   2[ 4p^2 - 9]   = 2 [ 2p + 3] [2p - 3]

3a-6b+9c  =  3 [ a - 2b + 3c]

pq+qr  = q [p + r]

21pq-7pr+6qs-2rs  = 7p [3q - r] + 2s[3q - r]  = [7p + 2s] [3q -r]
