Answer 1

Your Question : When a number is multiplied 5 times with itself the value comes 1445. find the number.

Hello !!
here is your answer ....

Let the number be = x

5 times of the number = 5x

When we multiply both , we get = 1445

So,

5x * x = 1445

$\bold{\underline{Divide\: both \:sides\: by \:5}}$

(5x * x)/5= 1445/5

x*x= 289

x² =289

$\bold{\underline{multiply\: both \: sides \: by\: sq.root}}$

√x² = √289

x=√289

x=17

So the answer is $\bold{17}$

$\bold{\underline{verification}}$

x*5x=1445

17*5(17)=1445

17*85=1445

1445=1445
