Find the product. (a^2)xx(2a^22) x (4a^26)

(3a^(2)b)xx(4a^(2)b)xx(-2)

Multiply: (-3a^2) xx (4a^2b) xx (-2)

Let's multiply :- (-3a^2) xx (4a^2b) xx (-2)

What will come in place of question mark (?) in the following questions ? 35152 xx (?)/(26) xx (?)/(26) xx (?)/(26) = 31250

The area of the greatest circle which can be inscribed in a square whose perimeter is 120cm, is (a) (22)/(7)xx((7)/(2))^(2)cm^(2)(b)(22)/(7)xx((9)/(2))^(2)cm^(2)(c)(22)/(7)xx((15)/(2))^(2)cm^(2)(d)(22)/(7)xx(15)^(2)cm^(2)

Find the sum (1xx2)/(3!)+(2xx(2)^2)/(4!)+(3xx(2)^3)/(5!)+ . . . +(20xx(2)^20)/(22!)

If (3^(a+3) xx 4^(a+6) xx 25^(a+1))/(27^(a-1) xx 8^(a-2) xx 125^(a+4)) = 4/(15^(26)) , then the value of sqrt(a+9) is:
