Question 813406
Here's what you've stated before {{{(-5^4)^2-7(1^12-1^3)}}} To know how is this solved u must follow the PEMDAS so {{{(-5^4)}}} is equal to 625 so <b>In raising a constant or variable, keep in mind that if the exponent of the constant is an even number the result is always postive and otherwise if the exponent is an odd number</b> so continuing the next we are going to solve is the exponent of 625 which is 2 so {{{(625)^2=390625}}} 390625 at the first part Let's see in the last {{{-7(1^12-1^3)}}} so {{{1^12=1}}} and {{{1^3=1}}} it stated the minus sign between the numbers so {{{1-1=0}}} the next step is the -7 to remove it {{{-7(0)}}} any number multiplied by zero is zero so the last and final part is combining the 2 parts {{{390625+0=390625}}} it's the correct answer :)
