Answer:

10/13

Step-by-step explanation:

There are 52 cards in a standard deck. There are 4 queens (queen of spades, clubs, hearts, diamonds) and 36 (2 - 10 of four suites) number cards. Therefore the probability of drawing a queen or a number card is (4 + 36)/52 = 40/52 = 10/13.

Write each equation in exponential form.
vichka [17]

Answer:

The exponential form of equation  log_{6}(216)=3  is (6)³ = 216

Step-by-step explanation:

The exponential equation of  log_{b}(a)=c  is a=b^{c} , where b is the base, c is the exponent of b and a is the value of b^{c}

Ex: log_{2}(8)=3 , its exponential function is 2^{3}=8

Now let us solve the question

∵ log_{6}(216)=3

∴ The base is 6

∴ The exponent is 3

∴ The answer is 216

∴ The exponential equation is (6)³ = 216

The exponential form of equation  log_{6}(216)=3  is (6)³ = 216
