Answer:
Step-by-step explanation:
<h3>Given</h3>
<h3>To find</h3>
- log6 15 in terms of a and b
<h3>Solution</h3>
<u>Rewrite the given</u>
- log9 2 = a ⇒ log2/log9 = a ⇒ 1/2*log2/log3 = a ⇒ log3 = 1/2*log2/a
- log5 4 = b ⇒ log4/log5 = b ⇒ log5 = 2*log2/b
<u>Rewriting the log6 15:</u>
- log6 15 = log15/log6= (log 5 + log3)/(log2 + log3)
<u>Substitute as follows:</u>
- (log 5 + log3)/(log2 + log3) =
- (2*log2/b + 1/2*log2/a)/(log2 + 1/2*log2/a) =
- (2/b + 1/(2a))/(1 + 1/(2a)) =
- (4a + b)/2ab ÷ (2a + 1)/2a =
- (4a + b)/(2ab + b)
Answer:
formula to find area = (1/2) b h
= (1/2) x Base x Height
substitute the values
= (1/2) x 18 x 12
= 108 cm2
