Question

Help, teachers asking me to do this independently but I barely understand. Help ASAP!!!

Answer 1

Answer:

9

Step-by-step explanation:

Use PEMDAS to solve it.

2 3 - (8-4) + 5 =

First: 2 3 - (4) + 5 =

Second: solve the 2 to the power of 3 exponent

2×2×2=8 (2×2=4 then 4×2=8)

So, 8 - 4 + 5 =

Third: 4 + 5 =

Last: 9

Answer 2

${{\rm{ {2}^{3} - (8 - 4) + 5 }}}$

${{\rm{\implies \: calculate \: the \: power}}}$

${{\rm{ {2}^{3} = 8 }}}$

${{\rm{ 8 - (8 - 4) + 5}}}$

${{\rm{ 8 - 4 + 5}}}$

$\boxed{\begin{array}{}{{\rm\red{\implies \: = 9}}}\end{array}}$
