(a) 5^31-5^29 = 5^29(5^2-1)

= 5^29(24)
= 5^29(6)(4)
=5^26(6)*[(5)(5)(4)]
=5^26(6)*100
(b) 25^9+5^17 = 5^18+5^17
=5^17(5+1)
=5^17(6)
=5^16[(5)(6)]
=5^16*30
(c) 27^10â€“9^14 = 3^30-3^28
=3^28(3^2 -1)
=3^28(8)
=3^27[(3)(8)]
=3^27*24

Find the radius if mADB=270° and length is 61.26 meters

love history [14]

Given:

In the given circle, ∠ADB = 270° and length of ADB = 61.26 m

To find the radius of the circle.

Formula

The formula to determine the radius is given by

$arc \ length =(\frac{\theta}{360})2 \pi r$

Substituting arc length = 61.26, $\theta= 270$ , we get;

$61.26 =(\frac{270}{360})2 (3.14) r$

$61.26 =4.71 r$

$13=r$

Thus, the radius is 13 m
