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

Answer 1

The standard form of ( 6.31×
`10^(5)` ) + (2.6 ×
`10^(4)` ) = 65.7 ×
`10^(4)`

Step-by-step explanation:

As given,

( 6.31×
`10^(5)` ) + (2.6 ×
`10^(4)` ) = ( 6.31×
`10^(4)`×10 ) + (2.6 ×
`10^(4)` )

=
`10^(4)` ( 6.31×10 + 2.6 )

=
`10^(4)` ( 63.1 + 2.6 )

=
`10^(4)` ( 65.7 )

= 65.7 ×
`10^(4)`

So, the standard form of ( 6.31×
`10^(5)` ) + (2.6 ×
`10^(4)` ) = 65.7 ×
`10^(4)`
