Question

Order of operations (PEMDAS) 3×(8×4+4^2)-9

Answer 1

3 * (8 * 4 + 4^2) - 9

Exponents come first

3 * (8 * 4 + 16) - 9

Next is multiplication

3 * (32 + 16) - 9

Finish parentheses

3 * (48) - 9

Multiply

144 - 9

Subtract

135

Answer 2

Answer:

$\boxed{=135}$

Step-by-step explanation:

PEMDAS stands for:

P-Parenthesis

E-Exponents

M-Multiply

D-Divide

A-Add

S-Subtract

That came from left to right.

First, calculate with parenthesis and exponents first.

$8*4+4^2=4*4=16$

$8*4+16$

Then, multiply from left to right.

$32+16$

Add from left to right.

$32+16=48$

$3*48-9$

Next, multiply from left to right.

$48*3=144$

Finally subtract from left to right.

$144-9$

Final answer: $\boxed{=135}$
