i am confused on this question -[(1.2+4.2)(0.7-0.5)^3]/(-0.2^4)
Thanks in advance
+4473 Ok, we need parentheses to get a clear understanding of what is going on because there are negatives, subtraction signs and exponents.
However, what is stated is that you first add 1.2 and 4.2 together and subtract 0.5 from 0.7. Also, for the denominator, I assume you want (-0.2)^4 (to the fourth power -- [-0.2*-0.2*-0.2*-0.2].)
Then, you take the answer from 0.7 - 0.5 and cube it (to the third power - ^3 - [0.2*0.2*0.2]).
Multiply that with 1.2 + 4.2. Add a negative sign or change a double negative into a positive.
Now divide the numerator by the denominator while remembering to keep track of negatives.
