`(14.2)^(2)+(16.4)^(2)-(17.9)^(2)=?+32.99`

(32.51)^(2)-(17.45)^(2)=?

If (4)^(a+5) (16) ^(2a)(32)^(4)=(16)^(3a) then a =___

factorize (1)9x^(2)-16y^(2),(2)2a^(5)-32a

Evaluate : ((1)/(4)) ^(-2) - 3 (32)^((2)/(5)) xx ( 7) ^(0) +((9)/(16))^(-(1)/(2))

A common tangent to 9x^(2)+164;y^(2)-x+4=08x^(2)+y^(2)-12x+32=0

Which one of the following is true? 1/2<9/(13)<3/4<(12)/(17) (b) 3/4<9/(13)<1/2<(12)/(17) (c) 1/2<3/4<9/(13)<(12)/(17) (d) 1/2<9/(13)<(12)/(17)<3/4

The value of ((9^(2)xx18^(4))/(3^(16))) is a.(3)/(2) b.(4)/(9) c.(16)/(81) d.(32)/(243)

The value of sum_(r=1)^(15)(r2^r)/((r+2)!) is (a). ((17)!-2^16)/((17)!) (b). ((18)!-2^(17))/((18)!) (c). ((16)!-2^(15))/((16)!) (d). ((15)!-2^(14))/((15)!)

The value of sum_(r=1)^(15)(r2^r)/((r+2)!) is (a). ((17)!-2^16)/((17)!) (b). ((18)!-2^(17))/((18)!) (c). ((16)!-2^(15))/((16)!) (d). ((15)!-2^(14))/((15)!)

The value of sum_(r=1)^(15) (r2^(r))/((r+2)!) is equal to (a) ((17)!-2^(16))/((17)!) (b) ((18)!2^(17))/((18)!) (c) ((16)!-2^(15))/((16)!) (d) ((15)!-2^(14))/((15)!)
