Answer» (a) answer is x=5(b)answer is x=3 (a)answer is X =5(b)answer is X=3 (a) answer is x=5(b) answer is x=3 (a) 2(x) =32 >2(5)=32 Hence x=5(b) (-4) x=(-64) >(-4) (3) =(-64) Hence x=3 x = 5 x=3 answer a. answer is x =5b.answer is x = 3 [a] = x=5[b) = x=3 answer (a)= 5answer(b)=3 2^5=32 option (a) is ture dear friend it is answer x=3 dear friend it answer (1) x=5, (2) x=3 (a) answer is X=5(b) answer is X =3 in part a x=5in part b x=3 (a) 2*2*2*2*2=32 and (b) 4*4*4=64 A's answer x=5 and B's answerx=3 (a)answer x=5. (b)answer x=3 (a) x=5 (b) x=3this is the answer x ki value 5 honi hh taki 32 aye x=5 2*2=4 '4*2=8 ;8*2=16;16*2=32 in (a) x=5 and in (b)x=3 x=52 ka 5 bar guna 32 hoga 2*2*2*2*2=32then x=5 for (a) answer is 5 2^5=2*2*2*2*2=32(b) answer is 3 (-4) ^3=-4*-4*-4=64 x=5x=3 respectively (a) answer is x=5(B) answer is x=5 value of x in ques a is 5 and in b is 3 (a) answer is x= 5(b) answer is x= 3 (a) x=5(b) x=3as 2 the power 5 is 32 by putting x=5 both RHS and LHS will be equal. for (b) -4 the power 3 =-64(-4)*(-4)*(-4)=-64 1 answer is 2 ki power 5 (a) x=5because 2 to the power of 5 will be 322*2*2*2*2=32(b) x=3-4*(-4)*(-4)=-64 5 and 3 is the answer 2^5 equals to 32 and -4 ^ 3 = - 64 (a)answer is x=5(b) answer is x=3 a) answer is x=5b) answer is x=3 (a) is true number is x=5(b) is true number is x=3 (a)x=5(b)x=-4. theek hai samajh gaye A = 2 ki power 5B =(-4) ki power 3 x=5as 2 power 5=32-4powers 5 =-64 (a) x= 5 answer( b) x= 3 answer (a) answer x=5(b) answer x=3 answer _a. x=5,b. x=3 (a) answer is x=5(b)answer is x=3ok a.) 5(2^5= 2*2*2*2*2=32)b.) 3 ((-4)^3 = (-4)*(-4)*(-4)=-64 |
