Question

solve all the problems

Answer 1

Answer:

1) 6a^2

2) 8^3/4

3) (3m) ( m + 2n )

4) 15

5) 1

6) 20

Step-by-step explanation:

1) 3a *2a

= 6a^2

2) 8^1/2 *8^3/2

= 8^1/2*3/2

= 8^3/4

4) cuberoot of 3375

= 15 *225

=15*15*15

Therefore cuberoot of 3375 is = 15

3) 3m^2 + 6mn

= 3m( m + 2n )

=( 3m ) (  m + 2n )

5) 5% of 400

= 400/100 *5

= 4*5

= 20
