(-5.12) - (-4.7) (7.021)
=(0-5.12)-(0-4.7)×7.021
=-5.12-(0-4.7)×7.021
=-5.12- 4.7×7.021
=-5.12- 32.9987
=27.8787

Simplify. (-5.12) - (-4.7) (7.021)

Remember the order of operations PEMDA Parenthesis, Exponents, Multiply and divide, Add and subtract.

First multiple -4.7*7.021 to get a -32.9987
this leaves -5.12 - (-32.9987)
-5.12+32.9987
= 27.8787 rounded to two decimal places is 27.88

7 +8(x4 -8) =7
7 + 8(x^4) - 8(8) = 7
7 + 8x^4 -64 = 7
7 -64 + 8 x^4 = 7
-57 + 8x^4 = 7
-57 + 57 + 8x^4 = 7 + 57
8x^4 = 64

8x^4/8 = 64/8

x^4 = 8
sq rt of x^4 = sq rt of 8
x = 2.8284 or 2.83
