Question

Work out the value of (6.31 x 10^5)+(2.6 x 10^4)
Give your answer in standard form

Answer 1

`(6.31* 10^(5))+(2.6* 10^(4))\implies 6\underline{31000}+2\underline{6000} \implies \text{\LARGE 657000}`

Answer 2

Answer: standard form of (6.31×10⁵ ) + (2.6×10⁴) is 65.7 × 10⁴.

What is a simplification of an expression?

Usually, simplification involves proceeding with the pending operations in the expression.

Simplification usually involves making the expression simple and easy to use later.

As given,

(6.31×10⁵ ) + (2.6×10⁴) = ( 6.31× 10⁴ ×10 ) + (2.6 × 10⁴ )

= ( 6.31 × 10 + 2.6 )

= ( 63.1 + 2.6 )

= ( 65.7 )

= 65.7 × 10⁴

Hence, the standard form of ( 6.31× 10⁵) + (2.6 × 10⁴) = 65.7 × 10⁴.
