guys pls
help me through this

Answer 1

Answer:

Question 1) a) 8⁴=8×8×8×8=4096

b) (-8)³=(-8)(-8)(-8)= - 512

c) 9⁴=9×9×9×9=6561

d) (-7)³= (-7)(-7)(-7)= - 343

Question 2) (-2/2)²×(1/2)³×(2/3)³

= (-1)²× (1/2×2/3)³

= - 1×3^-3

= - 3^-3 or - 1/27

Question 3) a) 5²×5⁴×5⁴×5⁴×5^7

=(5)^2+4+4+4+7

= (5)^21

b) 2^5×2^5

= (2)^5+5

=(2)^10

c) 3^6×3^7×3^5

= (3)^6+7+5

=(3)^18

d) 3^9×3^4×3^3×3^8

= (3)^9+4+3+8

=(3)^24

Question 4) if x=1 and y=5 then the value of the given equation after putting values will be : (1/5)¹

= 0.2

Question 5) a) 0×10²+0×10³+0×10³+5×10^5×9×10^6

=95,00,000

b) 0×10¹+9×10⁴+2×10²+1×10^5+0×10^7

=1,90,200
