(Input only whole numbers.)​

Answer 1

Answer:

91

Step-by-step explanation:

Use PEMDAS:

Exponents and multiplying before adding.

$3^4+2*5\\\rightarrow 3^4=81\\81+2*5\\\rightarrow 2*5=10\\81 + 10 =91$

Answer 2

Answer:

91

Step-by-step explanation:

For this problem, you have to remember PEMDAS.

Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

That's the order that you must do things in an equation.

So the $3^{4}$ would be first.

$3^{4}$ is like 3 x 3 x 3 x 3.

3 x 3 x 3 x 3 = 81

Then do the 2 · 5.

2 · 5 = 10.

Finally, add them together:

81 + 10 = 91
