4times the square root of 7 to the third power in exponential form

Do you mean 4 * sqrt(7 * 7 * 7) ?

If that is what you mean, it can be broken apart like this 4 * sqrt(7 * 7) * sqrt(7)

You can always do something like that. The square root of 7*7 is 7

Try it with your calculator. Put in √(7 * 7)= you should get 7.

So the answer is 4 * 7 * sqrt(7) = 28 * sqrt(7)

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
