Roger's evaluation of an expression is shown.

2(1+3)^3-5^2=

step 1: 2(4)^3-5^2=

step 2: (8^3)-5^2=

step 3: 24-10=

step 4: 14

describe all of the errors roger made with his work, then correctly evaluate the expression.

my 2(1+3)^3-5^2=
4
2*4^3-5^2=
2*64-25=
128-25=103

how do i describe what he did wrong?

power property.

x=half

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

angle efh= angle egh
