Question

13. ( (4) frac{8(3 cdot 75)^{3}+1}{(7 cdot 5)^{2}-6 cdot 5}=frac{(2 times 3 cdot 75)^{3}+1}{56 cdot 25-6 cdot 5} )
( =frac{(7 cdot 50)^{3}+1}{49 cdot 75}=frac{421 cdot 875+1}{49 cdot 75} )
( =frac{422 cdot 875}{49 cdot 75}=8 cdot 5 )

# 8(3.75)” +1 (7.5)2-6.5 cjkoj gs 000.000 0 (1) 2.75 (3) 4-75 (4) 8.5 9
