Answer

3answer Use am÷an=(a)m−n and am×an=am+n and a−m=am1

∴(25+28)×(2)−7=(2)5−8×(2)−7

=(2)−3×(2)−7

=(2)−3−7=(2)−10=2101=10241

5 It is given that:

X[142536]=[−72−84−96]

The matrix given on the R.H.S. of the equation is a 2×3 matrix and the one given on the L.H.S. of the equation is a 2×3 matrix. 

Therefore, X  has to be a 2×2 matrix.

Now, let X=[abcd]

Therefore, we have:

[abcd][142536]=[−72−84−96]

⇒[a+4cb+4d2a+5c2b+5d3a+6c3b+6d]=[−72−84−96]

Equating the corresponding elements of the two matrices, we have:

a+4c=−7b+4d=2
