(4/15+2/3)•(3/8-1/4)=14/15*1/8=7/15*1/4=7/60=0,116

Answer 2

Ответ:1)4/15+(2/3)⁵=5/15+10/15=14/15

2)3/8-(1/4)²=3/8-2/8=1/8

3)14/15*1/8=7*1/15*4=7/60

Answer 3

To solve this expression, you can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this case, you have parentheses, multiplication, and subtraction to perform.

Let's break it down step by step:

1. First, simplify the expressions inside the parentheses:

   (4/15 + 2/3) = (4/15 + 10/15) = 14/15

   (3/8 - 1/4) = (3/8 - 2/8) = 1/8

2. Now, multiply the simplified results:

   (14/15) * (1/8) = (14 * 1) / (15 * 8) = 14/120

3. Simplify the fraction further by finding the greatest common divisor (GCD) of 14 and 120, which is 2:

   (14/2) / (120/2) = 7/60

So, (4/15 + 2/3) * (3/8 - 1/4) = 7/60.
