Question

pls help me in this 3 questions... ​

Answer 1

Step-by-step explanation:

• Q2:

i) : Anything to the power zero is 1. Therefore the answer is 3.

ii) : According to the law of indices,

a^m/a^n= a^m-n

this gives,

(-17)^6/(-17)^5= (-17)^6-5

= (-17)^1

= (-17)

Q3) : Substituting tge values given, we get

i) 116

ii) -228

Answer 2

Answer & Step-by-step explanation:

Q1) 4 rational numbers between -2/3 to -1/5

If you look at it in decimal form -0.6 to -0.2

-0.5, -0.4,-0.32, -0.3,

When we convert to fractions we get  

-1/2, -2/5, -8/25, -3/10

Q2)

   i) 2^0 + 7^0 + (-3)^0  = 1 + 1 + 1 = 3

   ii) (-17)^6 /(-17)^5 = -(17) ^ (6-5) = -17

Q3) m=2 n=-3 p=-4

   i) 3m^2n^2 - 2p = (3 * (2^2) * (-3) ^ 2) - 2*(-4) = 116

   ii) -11mpn + 3np = (-11 * 2 *-4 * -3) + (3 * -3 * -4) = -288
