Answer:

a = 6

b = 3

c = 64

d= 64

Step-by-step explanation:

1. Apply the quotient of powers:

(-2)^a / 4^b

In the given expression:

4^5(-2)^9/4^8(-2)^3

base same then the powers are subtracting if the bases are in numerator and denominator

i.e a^m/a^n = a^{m-n}

Solving:

=(-2)^{9-3}/4^{-5+8}\\=(-2)^6/4^3

therefore, the values of a and b are: a = 6

b = 3

2. Evaluate Powers

c/d

We have

(-2)^6/4^3

When power is even negative sign changes into plus sign

64/64

Therefore, we get the values of c and d

c = 64

d= 64

The shadows of two vertical poles were measured at the same time to be 6m and 15m long. If the first pole is 8cm long, find the
son4ous [18]

Answer:

20 cm

Step-by-step explanation:

Shadow of vertical poles : 6m ; 15m

Length of poles : 8cm ; h

8cm long pole = shadow length, 6m

h cm long pole = shadow length, 15 m

Using cross multiplication :

8cm * 15 m = h cm * 6m

120 = 6h

h = 120 / 6

h = 20 cm

Height of second pole = 20cm
