Question

Будь ласка допоможіть : 27⁷+3¹⁸ кратне 7​

Answer 1

27⁷ + 3¹⁸ = (3³)⁷ + 3¹⁸ = 3²¹ + 3¹⁸ = 3¹⁸*(3³ + 1) = 28*3¹⁸ = 4*7*3¹⁸

в произведении если один из множителей кратен 7, то и все произведение кратно 7

Answer 2

27⁷ + 3¹⁸ is a mathematical expression that involves exponentiation and addition. To calculate the value of this expression, we need to evaluate each term separately.

Let's start with 27⁷. This means we need to multiply 27 by itself 7 times. Evaluating this expression, we get:

27⁷ = 27 * 27 * 27 * 27 * 27 * 27 * 27 = 387,420,489

Next, let's calculate 3¹⁸. This means we need to multiply 3 by itself 18 times. Evaluating this expression, we get:

3¹⁸ = 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 = 387,420,489

Now, we can add the two results together:

27⁷ + 3¹⁸ = 387,420,489 + 387,420,489 = 774,840,978

Therefore, the value of 27⁷ + 3¹⁸ is 774,840,978.
