7 * 0.04 = 7 * 4 *
7 times 0.04 equal 7 times 4 times ?

Solution

1 Cancel 77 on both sides

x\times 0.04=x\times 4xx×0.04=x×4x

2 Regroup terms

0.04x=x\times 4x0.04x=x×4x

3 Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}x

a

x

b

=x

a+b

0.04x={x}^{2}\times 40.04x=x

2

×4

4 Regroup terms

0.04x=4{x}^{2}0.04x=4x

2

5 Move all terms to one side

0.04x-4{x}^{2}=00.04x−4x

2

=0

6) Factor out the common term x

x(0.04-4x)=0

7 Solve for x

x=0,0.01

Done!
