Question

What value is equivalent to middle" class="latex-formula"> + 5 × 2 − 8?
A) −84
B) 8
C) 11
D) 20

Answer 1

Answer:

The correct option is C) 11

Therefore the equivalent value of

$3^{2}+5\times 2 -8 =11$

Step-by-step explanation:

Given:

$3^{2}+5\times 2 -8$

To Find:

Value of

$3^{2}+5\times 2 -8 =?$

Solution:

Use PEMDAS rule

PEMDAS is an acronym for the words

P - parenthesis,

E - exponents,

M - multiplication,

D - division,

A - addition,

S - subtraction.

For any expression, all exponents should be simplified first, followed by multiplication and division from left to right and, finally, addition and subtraction from left to right.

Here first we will calculate exponents

i.e $3^{2} = 9$

Second Multiplication

$5\times 2 =10$

Therefore Now we have

$9+10 -8$

Now ADD

$19 -8$

Now Subtract we get

$11$

Therefore the equivalent value of

$3^{2}+5\times 2 -8 =11$

Answer 2

$3^{2} +5 \times 2 - 2$ = 11

Step-by-step explanation:

$3^{2} +5 \times 2 - 2$

$= 9 + 10 -8$

$= 11$
