Question

find the product by suitable rearrangement b) 125 x 709 x 8​

Answer 1

Answer:

The value of X is 13.

Step-by-step explanation:

(125/8)×(125/8)^X=(5/2)^18

(125/8)^X+2=(5/2)^18

(5/2)^X+2+3=(5/2)^18

(5/2)^X+5=(5/2)^18

(5/2)^X=(5/2)^18-5

(5/2)^X=(5/2)^13

So, the value of X is 13

Answer 2

Answer:

709000

Step-by-step explanation:

[ (100+20+5) x 709 ] x (10-2)

[ (100 x 709) + (20 x 709) + (5 x 709) ]  x (10-2)

[ 70900 + 14180 + 3545 ]  x (10-2)

88625 x (10-2)

(88625 x 10) - (88625 x 2)  

886250 - 177250

709000
