Question

Evaluate the expression below: 10 • √64 – 5 • 4

Answer 1

`\huge\boxed{\sf 60}`

Explanation:

Given expression:

10 • √64 – 5 • 4

We know that, √64 = 8

So,

= 10 × 8 - 5 × 4

In an expression, we follow the order of DMAS:

D => Division

M => Multiplication

A => Addition

S => Subtraction

So, here we will multiply first.

= 80 - 20

= 60

`\rule[225]{225}{2}`
