Question

Log10+2log3-log2=loga then fing the value of a

Answer 1

Answer:

answer is 45 because log a + log b is log ab. then 10*3`2 is equals to 90. then log 90 minus log 2 is log 90 by 2 log 45. so a is 45

• $\orange{log(ab)=loga+logb}$

• $\blue{log(a÷b)=loga-logb}$

• $\green{log(a)^{m}=mloga}$

• $\orange{log10+2log3-log2=loga}$

• $\blue{log(\dfrac{10\times9}{2})=loga}$
