Evaluate :
4. `(-20 ) times (-5 )`
5. if `x div 1 = 8` , then x is equal to

(x^5 div x^4)^3 div x^2 = ?

5xx? = 4808 div 8

The value of 4.5 - ( 3.2 div 0.8xx 5 ) + 3xx 4 div 6 is 4.5 - ( 3.2 div 0.8xx 5 ) + 3xx 4 div 6 का मान ज्ञात करें |

If 5 ^(2x +1) div 25 = 125, find the value of x .

The value of 15.2 + 5.8 div 2.9xx 2 - 3.5 xx2 div 0.5 is equal to : 15.2 + 5.8 div 2.9xx 2 - 3.5 xx2 div 0.5 का मान ज्ञात करें ।

Evaluate [(5 ^(-1) xx 3 ^(-1))^(-1)div 6 ^(-1)]

The value of 8 div [ ( 9-5) div { ( 4 div 2 " of "4 ) - ( 8 div 8 " of " 15 ) + ( 4 xx 2 div 8 ) } ] is :

The value of 9xx6 div 24 +8 div 2 of 5-30 div 4 of 4 + 27 xx5 div 9 is : 9xx6 div 24 +8 div 2 of 5-30 div 4 of 4 + 27 xx5 div 9 का मान है :
