hi mate mark me as brainliest ............xd
Answer:
a) is 36
b) is 36000
c) is -512
10.a) is -8
10.b) is 4
Step-by-step explanation:
a) 2^2*3^2 (2^2 means 2*2 = 4 and
2*2 * 3*3 3^2 means 3*3 = 9 or
= 36 5^2 means 5*5 = 25)
= 4*9
= 36
b) 6^2*10^3 (We know how to do 2
= 6*6 * 10*10 square and now 10^3
*10 means 10*10*10 = 1000
= 36 * 1000 or 4^3 means 4*4*4 =
= 360000 64)
c) -2 * (-4)^4 (we even learn about
= -2 * -4*-4* 2^3 now what is power
-4*-4 4 power 4 is multiply
= -2 * 16*16 the same number 4
= -2 * 256 timesand even u
= -512 shuld multiply the sign)
( Now -*- = + )
10.a) (5x)^3 where x is -2/5
now substitute the value of x
(5*-2/5)^3
(-10/5)^3 [multiplied 5*-2]
(-2)^3 [divided -10/5 = -2]
-2*-2*-2
4*-2 [-*- = +]
-8
10.b) (-ab) ^2 where a = 2 and b =-1
Substitute the values of a and b
(-2*-1)^2
(2)^2 [-*- = +]
2*2
4
