Gnesinka [82]

Answer:

Step-by-step explanation:

a) 15 + 6x = 81

6x = 81 - 15

6x = 66

x = 11

b) 40 + 55h = 190

55h = 190 - 40

55h = 150

h = 2.7

c) (p + 7)/12 = 3

p + 7 = 36

p = 36 - 7

p = 29

Verify each of the following by evaluating the logarithms.<br> log10(103) + log10(104) = log10(107)
ioda

Answer:

log₁₀(10³) + log₁₀(10⁴)

= log₁₀( 10³ × 10⁴ )

= log₁₀( 10³⁺⁴)

= log₁₀( 10⁷)

Step-by-step explanation:

Given:

log₁₀(10³) + log₁₀(10⁴) = log₁₀(10⁷)

Now,

we know the property of log function that

log(A) + log(B) = log(AB)

therefore,

applying the above property on the LHS, we get

log₁₀(10³) + log₁₀(10⁴) = log₁₀( 10³ × 10⁴ )

also,

xᵃ + xᵇ = xᵃ⁺ᵇ

therefore,

log₁₀( 10³ × 10⁴ ) = log₁₀( 10³⁺⁴)

= log₁₀( 10⁷)

Hence,

LHS = RHS

Hence proved
